Rated for up to 600VAC and 250VDC, it uses the KLSR series' single-element silver-link design. It comes in an industrial cartridge format for installation in a compatible fuse block, clip, or holder. One detail matters when selecting this fuse: fast-acting KLSR fuses can open on harmless inrush currents from inductive loads such as motors, solenoids, and transformers, so they should not be substituted for a time-delay fuse simply because the amperage and voltage appear to match.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1A continuous current rating for equipment specifically designed around a 1-amp Class RK1 fuse.\u003c\/li\u003e\n\u003cli\u003eFast-acting operation provides quick response to overload and short-circuit conditions.\u003c\/li\u003e\n\u003cli\u003eThe current-limiting design helps reduce equipment damage from the heating and magnetic effects of short-circuit currents, according to the manufacturer.\u003c\/li\u003e\n\u003cli\u003eRated for a maximum of 600VAC, making the AC voltage rating an important part of replacement matching.\u003c\/li\u003e\n\u003cli\u003eAlso rated for up to 250VDC.\u003c\/li\u003e\n\u003cli\u003eSingle-element silver-link construction is a defining feature of the KLSR series.\u003c\/li\u003e\n\u003cli\u003eIndustrial cartridge construction provides the specified physical format for compatible installations.\u003c\/li\u003e\n\u003cli\u003eDesigned for mounting on a fuse block, clip, or holder.\u003c\/li\u003e\n\u003cli\u003eThe supplied holder reference is the LFR60030 Series.\u003c\/li\u003e\n\u003cli\u003eConfirm the non-indicating design when matching an existing fuse.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e KLSR001\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Description:\u003c\/strong\u003e FUS 600V F\/A CLASS RK1 1A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e KLSR\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Fast-Acting, Current-Limiting Fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Current Rating:\u003c\/strong\u003e 1A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum AC Voltage:\u003c\/strong\u003e 600VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum DC Voltage:\u003c\/strong\u003e 250VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC Interrupting Rating:\u003c\/strong\u003e 200,000A at 600VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Interrupting Rating:\u003c\/strong\u003e 20,000A at 250VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpening Characteristic:\u003c\/strong\u003e Fast-Acting (F)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Class:\u003c\/strong\u003e Class RK1\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFamily Style:\u003c\/strong\u003e Current Limiting\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction \/ Size:\u003c\/strong\u003e Industrial Cartridge\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElement Design:\u003c\/strong\u003e Single-element silver link\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndicating:\u003c\/strong\u003e No\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Method:\u003c\/strong\u003e Fuse Block \/ Clip \/ Holder\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecified Holder Series:\u003c\/strong\u003e LFR60030 Series\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMaterial Compliance and Certifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe supplied manufacturer information identifies a silver link as part of the KLSR series' single-element construction.
